Ron Paul’s campaign theme that rival Newt Gingrich is “not a conservative” continues today with a new 60-second TV ad in Iowa.

This will make Paul the first presidential candidate to air an attack advertisement on television in the first-in-the-nation voting state.

Donors have chipped in $850,000 so far during a three-day fundraiser launched Monday to fund ads in Iowa and New Hampshire, according to RonPaul2012.com.

The new Iowa ad is a shorter version of an earlier web video that calls into question Gingrich’s positions “on a group of issues dear to conservative voters,” Paul campaign aides said.

“Newt Gingrich: Serial Hypocrisy” is on Fox stations in Iowa today. It’s running at the same time as Paul’s other new ad, “Big Dog.”

The online version of Paul’s polished new attack ad caught buzz for zapping Gingrich on flip-flops on climate change, the individual health care mandate, Libya, U.S. Rep. Paul Ryan’s budget plan and other points.
